To all whom, t may concern:

Be it known that I, ALONZO ROAGH, a citizen of the United States,residing at Linton, in the county of Greene and State of Indiana, haveinvented certain new and useful Improvements in Acetylene Lamps, ofwhich the following is a specification, reference being had totheaccompanying drawimprovements and more particularly to that class Thisinvention `,relates to in lamps,

Vvof lamps in which acetylene gas is the fuel whichis burned. y

This lamp is particularly adapted for use by miners, but may be used formany other purposes such as vehicle lamps or the' like.

An object of the invention is theV provision of a lamp of this characterwhich is provided with an improved form of water distributer so that thewater will be" equally distributed to the carbi j A further object ofthis inventionis the provision of means for straining the gasgenerated'by the water and carbid to prevent any foreign matter frompassing into the outlet tube,` and rendering the lamp inoperative.

With these and other objects in view, as willbecome more apparent as thedescription proceeds, my invention consists in certain constructions,combinations, and arrangements of rparts to be hereinafter more fullydescribed, claimed and illustrated in the accompanying drawing, in whichFigure 1 is a front elevation of my device, and Fig. 2 is a verticalsection thereof.

Referring more particularly to the drawings, the numeral 1 designatesthe carbid container which is formed with a threaded neck 2 forengagement with the threaded flange 3 of the water reservoir 4. Thewaopening 5 which is suitably closed by a hingedly mounted vent cap 6.Aneek 7 is formed on the top of the water reservoir, and disposedthrough the opening in the neck is a rod 8, the upperend of which isoffset, as at 9, to form a handle. A 'central opening 10 is formed inthe base-plate 11 of the reserand depending Afrom the opening is a tube12 in which the lower end of the ro'd ,8- is slidably disposed.Extending through the flange 3 near the base plate 11 is a gas outlettube 13, in the outer end of which is threadably disposed a burner tip14, and a Specification of Letters Patent.

suitable reiiector 15 is of the outlet tube.v I

A cover plate 16 having a central opening 17, is slidablydisposed on thetube 12, the plate being of substantially the same diameter as theflange 3 to prevent the carbid from entering theoutlet tube 13. Securedto the bottom cally opposite the outlet tube'13, is aV lop 18, the plate16 being adapted to rest against the inner end of the tube13`and theloop 18 secured to the end plate 10 at a point diametriso that the platewillbe maintained A1n a e horizontal position within the angeby the neckof the carbid container. the cover plate 16 and adapted to surround theopening 17 therein, is a depending'water distributer'19, the distributercomprising a coiled wire which is tapered, as at 20, at the lowerend'thereof. -The coils of the wire are slightly spaced to allow waterfrom the reservoir to drain therethrough, thereby equally distributingthe water to the carbid. A disk of felt or other suitable i'ibrousinaterial 21 is disposed between the cover plate Connected tol 16 andthe bottom plate 11 of the water res.- f ervoir to strain the gasbeforeit enters the outlet tube, andv thereby prevent, the tube fromVbecoming clogged and rendering the lamp inoperative. y..

'If desired, an automatic sparking device may be secured in thereiiector 15 below the 4 burner 14, so that the use of matches to lightthe lamp willbe unnecessary. The lighter consists of a hollow plug 22which is secured in the wall of the reiiector, the inner endVL of theplug being bifurcated, forv the reception of a rotatably mountedabrasive wheel 23. Disposed in the hollow end i of the plug is a sparkproducing stick of 'material 24, and 'a follower nut 25 is threadedlydisposed o n the end of the plug to feed the stick 24 against the wall23. If desired, a spring 26 may be disposed between the nut and thestick so that the tension of thespring may be regulated by adjustingtheV nut, whereby the spring will normally maintain the stick inengagement with the wheel. 4

In the practical use of my lamp, the water reservoir is filled withwater through the filling opening 5, and carbid is placed in thecontainer l, whereupon the reservoir and vcontainer are connected. Uponraising the rod 8 the water will be allowed to flow through the pipe 12into the distributer 19, and as the lowerend' of the distributer, is

adapted to rest in the carbid, the Water will being generated, will passbetween the convolutions of the spring and thence up wardly through theopening 1T in the bottom plate 16, whereupon it will pass through thedisk Q1 into the out-let tube 13 to the burner. Upon rotation of thewheel 23, sparks will be produced by reason o;t` the trictionalengagement between the periphery of the wall and the end of the stick 24and the gas will be automatically lighted. Should the lower end of thewater pipe 12 become clogged, it will only be necessary to move the rod8 upwardly and downwardly to clear the opening and allow the Water topass freely into the carbid, through the spring 19.

W'hat is claimed is The combination with a lamp of the characterdescribed having a reflector surrounding the burner tip of `the lamp,Vof a tube fixed at one ot' its ends to the wall of the retlectoradjacentthe outer edge thereof and extending rearwardly'o the saine and belowthe reflector, the fixed end of said tube being jectinginwardly from theretlector wall, an abrasive wheel rotatably mounted between said earsand having its axis disposed in a plane at right angles to thelongitudinal axis of the reflector, the peripherv of said wheelprojecting beyond the plane of the outer edge oi the reflector wall, astick et sparking material slid-abby mounted in said tube7 a springarranged in the tube and bearing against the sparking stick to force thesame into frictional engagement with the abrasive wheel7 and a capthreaded upon the end of said tube to removably retain the provided withspaced ears pro.

spring therein and adjust the tension thereof.

ln testimony whereof I hereunto aliiX my signature 1n the presence oftwo witnesses.
